Dave Matthews Band-Why I Am tab

This album is different but really grows on you.
I apologize for this tab being rather blah but just getting the main parts across.
I'm not sure how to coomunicate the rhythm well so just use your ears.
Never made a tab before and I don't have a definite way to play this, mainly just the musical
notes.
Main Riff:
G-GG-G(octave)-GG-C-B
e|---------------------------|
B|---------------------------|
G|---------------------------|
D|--------5------------------|
A|----------------------3--2-|
E|-3---3-----3-3--3--3-------|
Main Riff when sing "Why I am" at the end.
e|-----------------------------|
B|-----------------------------|
G|-----------------------------|
D|--------5-------------3--2---|
A|---------------------------3-|
E|-3---3-----3-3--3--3---------|
Might be this at times too.

E|-3---3-----3-3--3--3----------|
*I like to just pound on a G chord, hitting the top deeper strings and then the higher
for the octave effect. Then just get those other notes in there however, either
or do a C chord and a C/B
Another part. Listen for it. First 3 notes are held longer and then quick on the A
notes.
